| 摘 要： | 以实际工程为例,通过选取相关单元参数,合理布置隔震支座,对该结构进行了多遇地震分析,分别对比隔震结构和普通结构的地震反应。在对隔震结构进行多遇地震分析的基础上,采用快速非线性分析方法,进一步对结构进行了罕遇地震下的隔震分析,对结构层间位移响应、层间剪力以及地震作用下能量分析进行了研究,同时分析了隔震支座在罕遇地震下的反应,研究表明该结构具有良好的隔震效果。

| Abstract: | An example of a practical project is taken through selecting the relevant parameters and arranging isolator in a reasonable way to conduct multi-earthquake analysis for such structure,the earthquake responses between isolated structure and common structure are compared.Based on the multi-earthquake analysis of isolated structure,a fast nonlinear analysis method is adopted to conduct further earthquake isolation research to the structure under major earthquake occurrence,besides,structural inner-layer displacement response,inter-laminar shear and energy analysis under earthquake effect are carried out,together with the isolator’s response under severe earthquake case.Through the above-mentioned studies,it is concluded that this structure has a good isolation effect. |
